Bush has proven to throw lots of strikes, but also lots of hittable balls that have produced early innings. Consistency will need to be the key for him.

He's on the 15-day disabled list, and is hoping to successfully rehab his left elbow, turning down season-ending Tommy John surgery. He'll also have to turn down his home run total once he comes back if he wants to keep a spot in the rotation.

If he can come back fully from minor knee surgery, this kid has a chance to become something special. With less than one hit given up per inning, and nearly a strikeout per inning, Gallardo should slide into the number two role with ease. He'll need to dominate if Ben Sheets can't keep healthy.

He's got all the potential in the world, and the Brewers will need it quickly with Yovani Gallardo on the disabled list and Parra now in the number five slot.

With his health goes the Brewers season. He hasn't been able to go a full campaign since 2004. If he does this year, and he gets his strikeout dominance back, the trickle-down effect to the rest of the rotation, the bullpen and the lessened pressure on the Brewers' bats should mean a division title.

His health is consistent - nine straight years with 30 starts. His performance wasn't consistent in 2007 after signing a big free-agent deal. He'll have to improve in April and May to produce at the time the Brewers hired him to, in October, where he historically shines.

Chosen over Claudio Vargas, who was released. He has major talent and can turn into more than just a four-or-five guy in the rotation if he harnesses his game.
